SPECIFICATION forming part of Letters Patent No. 757,312, dated April 12, 1904;

l Application filed -Tuly 21, 1903. Serial No. 166,462. (No model.)

. To all' whom t may concern:

Be it known that I, JAMES ELLwooD JONES,

a citizenof the United States of America, residing at Switchback, in the county of Mc- Dowell, in the State of West Virginia, have invented certain new and useful Improvements in Coke-Pullers, of which the following is a Specification. f-

This invention relates to a coke-puller designed to be operated by machine for pulling coke from coke-ovens, and it is Vparticularly adapted for discharging coke from beehiveovens. l l

The invention is herein shown as applied to a coke-puller comprising an underworking scraperoperative on its instroketo loosen coke forwithdrawal and on its outstroke to withdraw the loosened coke. A

The object of the invention is to insure the withdrawal of the full depth of coke on the outstroke. y

Figure 1 of the accompanying drawings represents a longitudinal vertical section on line 1 l of Fig. 2. Fig. 2 represents a plan, parts being broken out. y Y

The same reference-numbers indicate corresponding parts in both figures.

This coke-puller is designed to be mounted on a machine adapted to thrust it into and retract it from the oven'and swing it laterally in either direction to enable it to engage the coke at the sides of the oven. The machine shown in the expired United States Patent No. 446,936 maybe used for this purpose.

The coke-puller comprises an actuating-bar 10, which is preferably rigid throughout, the rear portion thereof having a rack-bar or rack-teeth 11, corresponding to the rack-bar c of said patent, and the front portion 12 having a longitudinal slot 13. A cross-bar 14 is integral with or connected to the front end of the portion 12 and provided near its opposite ends at opposite sides of the scraper with slotted eyes 15 and 16.

A scraper 20 is disposed on the front portion 12 of the bar 1() and in the form shown is adapted to slide thereon. This scraper is hollow and of wedge-like form and comprises a bottom plate 21, of a breadth equal to the lplate 22,'which extends upwardly and rearwardly from the front edge'of the bottom plate, and a back plate 24, which connects the inner edges of the bottom andtop plates and constitutes the thick side of the Wedge-like body. The top plate is provided with a transverse slot 23, and a transversefpintle-rod' 25 is disposed in a pintle-socket 26, attached to the plate 22 opposite the slot 23. The scraper l" is provided with a hollowshank cross-bar or stud 28. i

27, having a 1 An adjustable coke-holder 30, preferably comprising a plate 31, having pintle-sockets 33 and y34 at its opposite sides, is hinged to theplate 22 by means of the pintle-rod25 or otherwise. Thisplate in normal position lies over the outer face of the plate 22, below the slot 23, and is preferably provided with a rearwardly-projecting shank 32, which extends underneath the plate 22, above said slot. The front end of this plate is preferably beveled to coincide with the bottom of the bottom plate 21. The plate 31 is designed to lie flat against the upper faceof the top plate 22 of the scraper on the inward stroke thereof and to swing into upright operative position for engaging the coke on the outstroke. Any

'suitable means may be employed for shifting the position of theplate.- The means shown comprise slotted crank-arms 35 and 36, attached to the pintle-sockets 33 and 34 and extending inward substantially at right angles `to the plate 31. Levers40 and 50 are pvoted on studs, as 51, on the inner faces of the sides ofthe scraper. The lever is provided at its upper end with a stud 52, which engages the slotted crank-arm 36, andthe lever 40 is provided at its upper end with astud`42, which engages the slotted crank-arm 35. The lower end of-the lever 50 is provided with a stud 53, and the lower end of the lever 40 is provided with a' corresponding stud. These studs engage the slotted eyes 15 and 16, attached to the actuating-bar 10.

In the use of this coke-puller it is preferably mounted on a machine similar to that shown in said patent or any equivalent thereof. The coke-puller is thrust into the oven (Not shown.)

and retracted therefrom by the machine, or this might be done by hand. The drawings show the coke-puller in position for an inward thrust. On the instroke the wedge -like scraper moves over the bottom of the oven underneath the caked mass of coke a suiiicient distance to make a proper drawing thereorl and operates as a wedge to lift more or less of the coke under which it passes, usually breaking or separating1 said coke from said caked mass. The motion of the actuating-bar 10 is reversed at the end of the inward stroke and said bar is drawn backward preparatory to the outward stroke. During the rst part of the backward movement of said bar the scraper 20 remains stationary under the weight of coke behind it until the front end of the slot 13 in said bar engages the stud 28 of the shank of the scraper. During this backward movement of the bar 10 the cokeholder 30 is swung into vertical or approximately vertical operative position, as indicated by dotted lines in Fig. l. whereby it is adapted to engage a large mass of coke. The backward movement of the bar is continued and the outstrokel of the scraper is efected while the coke-holder is in upright position. Consequently the coke behind said holder is drawn out through the door of the oven. The first few strokes of the coke-puller are preferably in a direct line, two or more drawings being usually required to remove the coke throughout the. diameter of a coke-oven. After this is done lateral thrusts of the cokepuller are made first to one side and then to the other by means of the machine on which the cokepuller is mounted or otherwise.

The shank of the scraper may be in the `form of an elongated bar extending back of the machine or operator, and it may be provided with means for adjusting it into operative position independent of the resistance of the cok-e behind it. u

I claim as my inventionl. A coke-puller comprising an underworking wedge-like scraper movable over the bottom of a coke-oven, an adjustable coke-holder hinged to said scraper and provided with a crank-arm, a lever engaging said crank-arm, and an actuating-rod connected with said lever for swinging said coke-holder into operative position.
